Central condylar displacement with brain abscess from chronic mandibular osteomyelitis
Abstract In this case report, we describe a unique long‐term complication from undiagnosed mandibular osteomyelitis. A 53‐year‐old female who underwent a dental extraction complicated by chronic postoperative odontogenic infection and cutaneous parotid fistula formation 2 years earlier presented with acute mental status change, gradual unilateral facial nerve palsy (House‐Brackmann score V), and nontraumatic dislocation of the condylar head into the middle cranial fossa. The patient's chronic mandibular osteomyelitis led to glenoid fossa erosion, middle cranial fossa penetration, and temporal lobe abscess formation...

Animal Models for Bisphosphonate Related Osteonecrosis of the Jaws‐ An Appraisal
Abstract The prolonged use of bisphosphonates has been shown to cause a condition termed ‘bisphosphonate related osteonecrosis of jaws’ (BRONJ). BRONJ is a disease entity which has only been described relatively recently, and its multi‐factorial aetiology is yet to be fully elucidated. Therefore, the treatment of BRONJ lesions remains a challenge, and animal models are necessary to assist researchers in better understanding the disease. This has led to the recent publication of a number of studies utilising a variety of animal models of BRONJ. This review outlines the factors to be considered whilst selecting an anim...

Evaluation of the expression of p53, MDM2 and SUMO‐1 in oral lichen planus
ConclusionsThe results demonstrated overexpression of important proteins (p53 and MDM2) related to regulatory mechanisms of apoptosis in oral lichen planus, suggesting that there is a favorable environment for malignant transformation. The expression of SUMO‐1 in oral lichen planus was similar to normal mucosa and inflammatory fibrous hyperplasia, suggesting that alterations of this protein occur at later stages of carcinogenesis, since important overexpression occurred in oral epithelial dysplasia and oral squamous cell carcinoma.© 2013 John Wiley & Sons A/S

Exploiting PI3K/mTOR Signaling to Accelerate Epithelial Wound Healing
Abstract The molecular circuitries controlling the process of skin wound healing have gained new significant insights in recent years. This knowledge is built on landmark studies on skin embryogenesis, maturation, and differentiation. Furthermore, the identification, characterization, and elucidation of the biological roles of adult skin epithelial stem cells and their influence in tissue homeostasis have provided the foundation for the overall understanding of the process of skin wound healing and tissue repair. Among numerous signaling pathways associated with epithelial functions, the PI3K/Akt/mTOR signaling route has g...

Urban Legends Series: Oral Leukoplakia
Abstract To date, the term oral leukoplakia (OL) should be used to recognize “predominantly white plaques of questionable risk, having excluded (other) known diseases or disorders that carry no increased risk for cancer”. In this review, we addressed four controversial topics regarding oral leukoplakias (OLs): (1) Do tobacco and alcohol cause OLs ? (2) What percentage of OLs transform into oral squamous cell carcinoma (OSCC)? (3) Can we distinguish between pre‐malignant and innocent OLs? (4) Is proliferative verrucous leukoplakia (PVL) a specific entity or just a form of multifocal leukoplakia? Results of extensive l...

Centralisation To Fewer Surgeons Results In Better Survival After Oesophageal Cancer Surgery
Patients who undergo surgery for oesophageal cancer have a much greater chance of long term survival if the operation is carried out by a surgeon who has performed this particular operation many times before. This according to a new, large-scale study conducted by researchers at Karolinska Institutet in Sweden, which is published in the Journal of Clinical Oncology. In their article, the researchers conclude that oesophageal cancer surgery should be concentrated - or centralised - to fewer surgeons. Surgery is the most widely established curative treatment for oesophageal cancer...

Expression levels of endogenous hydrogen sulfide are altered in patients with allergic rhinitis
Conclusions:The current findings indicate that, in parallel with increased expression levels of CSE and CBS, H2S is upregulated in nasal mucosa and plasma of allergic patients. Based on localization of CSE and CBS, H2S may play multiple functions in human nasal mucosa, contributing to the development of allergic symptoms such as rhinorrhea, sneezing, and nasal stuffiness.

Impact of obesity on uvulopalatopharyngoplasty success in patients with severe obstructive sleep apnea: a retrospective single-center study in Taiwan.
Conclusion: Our findings suggest that, in Asian patients with severe obstructive sleep apnea (OSA), obesity is a better predictor of uvulopalatopharyngoplasty (UPPP) failure than Friedman stage III. Objectives: This study evaluated UPPP success rates in obese and non-obese Asian patients treated for severe OSA. Methods: Records of patients who underwent UPPP for treatment of OSA were retrospectively reviewed. Preoperative and postoperative apnea/hypopnea index (AHI) and Epworth Sleepiness Scale (ESS) score, and Friedman stage were compared in non-obese (body mass index (BMI) <27 kg/m(2)) and obese (BMI ≥27 kg/m(2)) pa...

Detection of paranasal ectopic adrenocorticotropic hormone‐secreting pituitary adenoma by Ga‐68‐DOTANOC positron‐emission tomography–computed tomography
We present an extremely rare case of a patient with CS caused by an ectopic ACTH‐secreting pituitary adenoma (EAPA) of the ethmoid sinus. The tumor was identified by positron‐emission tomography–computed tomography (PET/CT) using the somatostatin receptor analogue Ga‐68‐DOTANOC. Transnasal endoscopic resection was performed and the patient showed significant clinical improvement with normalization of the endocrine pituitary axis. Immunostaining showed a somatostatin receptor 2 and 5‐positive ACTH‐producing adenoma. In patients with ectopic ACTH secretion, Ga‐68‐DOTANOC‐PET/CT may play an important role ...

Voice conversion in cochlear implantation
Conclusion:The strong cueing to F0 within the voice conversion algorithms suggests that CI users are able to utilize temporal periodicity information for some pitch‐related tasks. Limitations on spectral channel information experienced by CI users may result in poorer performance with voice conversion algorithms due to distortion of speech formant information and degradation of the spectral envelope.

Implementing guidelines for follow-up after surgery with ventilation tube in the tympanic membrane in Norway: a retrospective study
Conclusions: The methods for guideline implementation were successful in securing consultations for follow-up care in general practice. Lack of guideline adherence in the hospital can partly be explained by the lack of quality of the guideline. Further studies are needed to evaluate the quality of controls done by the GPs in order to consider implications for follow-up after VT surgery.

Hemorrhage From the Cricothyroid Artery Due to Cricothyrotomy: A Case Report
Ensuring a secure airway remains the first step in the management of any critically ill patient. Various techniques for doing so exist and range from jaw thrust, head tilt, and chin lift to oral and nasotracheal intubation. Cricothyrotomy has become the quickest, safest, easiest, and most reliable way of securing the airway after failed attempts at oral or nasotracheal intubation. Nonetheless, cricothyrotomy is not a procedure that is frequently required or performed, especially with the development of intubation aids such as video laryngoscopy and bronchoscopy. As a result, many practitioners have very little experience i...

The Head, Neck, and Systemic Manifestations of Levamisole-Adulterated Cocaine Use
The objective of this review is to increase awareness of these manifestations among oral and maxillofacial surgeons. LAC exposure through inhalation, nasal insufflation, or injection can induce cutaneous vasculopathy and hematologic abnormalities such as neutropenia or agranulocytosis. Unlike other vasculopathies involving the skin, LAC-induced vascular injury frequently manifests with purpuric and necrotic lesions that involve the face and ears. Oral manifestations have also been reported but are not yet well characterized. The aforementioned hematologic manifestations are not uncommon, and patients exposed to LAC are pot...

Intra-oral injury assessment and recording in evacuated military personnel
Intra-oral trauma is commonly found in the multiply injured serviceman. Many evacuated patients remain intubated and unconscious producing difficulty in diagnosing intra-oral injury. Delays in recognition and treatment of such injuries can result in significant preventable long-term morbidity. It has therefore been recommended as a standard that all UK service personnel evacuated to the Royal Centre for Defence Medicine (RCDM) should have an intra-oral examination recorded in the hospital notes.

The role of the larynx in chronic cough.
Abstract Cough lasting more than 8 weeks is considered chronic. If the classic causes of chronic cough have been discarded, vagus nerve sensory disturbances are currently considered the most important etiological cause. Patients with chronic cough of laryngeal origin have associated symptoms such as globus, dysphagia, dysphonia, dyspnoea and/or stridor. These patients are more likely to have paradoxical vocal fold movement. There is a higher cough reflex sensibility and neuropathic laryngeal response, mainly caused by viral infection or reflux. The cough associated with reflux has 2 mechanisms: Exposure to acid in ...

Clinical analysis of patients with idiopathic sudden sensorineural hearing loss and benign paroxysmal positional vertigo.
Conclusions: Thirteen (5.4%) of patients with idiopathic sudden sensorineural hearing loss (ISSNHL) had benign paroxysmal positional vertigo (BPPV). Most of the patients showed profound hearing loss and had BPPV of the lateral canal. BPPV in patients with ISSNHL may have no influence on hearing recovery. Objectives: BPPV occurs in 8.6-12.7% of patients with ISSNHL; however, the role of BPPV in hearing recovery remains controversial. Therefore, we investigated hearing outcomes in the patients, including the distribution of initial hearing threshold, the type of canal involved, and the number of repositioning maneuvers perfo...

Repair of long type IV posterior laryngeal cleft through a cervical approach using cricotracheal separation
Abstract A female infant with CHARGE syndrome and a long type IV cleft extending to within 5 mm of the carina underwent transcervical repair at 5 weeks of age. The trachea was transected from the cricoid cartilage and was peeled off the esophagus. The front of the esophagus and the back of the trachea were repaired while still ventilating the patient. The trachea was reconnected to the cricoid cartilage. This technique obviated the need for a sternal split, thoracotomy, cardiopulmonary bypass, or extracorporeal membrane oxygenation. It improved visibility, access, airway stability, and coverage of the anastomosis with peri...

Effects of guidelines on adeno-tonsillar surgery on the clinical behaviour of otorhinolaryngologists in Italy
Conclusions: The recommendations first developed in Italy in a 2003 policy document and then resumed in guidelines in 2008, were not implemented by ENT units involved in the survey. The study highlights the fact that the indications for adeno-tonsillar operations are based on the overall clinical presentation (comorbidity) rather than on a single symptom. Guidelines are necessary to give coherent recommendations based on both the findings obtained through randomized controlled trials and the data collected from observational studies.

Management of cerebrospinal fluid otorrhea.
CONCLUSIONS: Cerebrospinal fluid otorrhea is a rare entity in otorhinolaryngological pathology.
